.THERMOMETER Application filed March 8, 1924:.:v Serial No. 697.,762. l

My invention relatesto improvementslin thermometers and more particularly tothat f type of thermometer which is adapted to :be applied to automobiles, aeroplanes and other means of conveyance.

An important 'object of the invention the provision of a device of the'above mentioned @character lwhichv can be readily 4mounted-upon the windshield o'r'framevvorlr of an automobile or on appropriate .parts-cf .i other means of conveyance,and which when Y located on a-closedtype of,.car,w ill bl/incapable of Iremoval yfrom without. .-z

Another objectof .the vlinvention '."s to provide a device of.` -this character whichl isfca-` pable'of adjustment so as tobeviewed from different angles. j

A further object of theinvention isto provide a device. of the above mentioned character `which will be protectedfrom the weather but will give the temperatureof the.

.air on the outside of the vehicle.

'Anotherobject of the invention is 'the` Ifo-'l vision of a device of this lcharacterw ichV will besimpleof construction, easy `to manufacture, strong and durable.

Other objects and advantages of my in-v vention will beapparent during the course of the following description.

In the accompanying form a partof this specification yand in which like' numerals are employed to desig-v lnate like parts throughout the same:

The larm 26 carries a set screw 28 which clamps 'thedevice to the v'Windshield or framework. The supporting arm 19 is alsooffsetflaterally as at 2 9 so that the device may be clamped to the side Vframeof lthe windshieldand be visible from within the car, as'lillustrated in Figure .11.

. The.` thermometer tube 30 is attached to the transparent support 3l, preferably vcelfrom'l'the side to which the thermometer v30 is attached, and vhas its side'p'ortions cut away at 34. Inassembling, the transparent thermometer support 3 1 is bent Vupon itself into a'cylindrical formationand lslipped within the glass tube 14, see Figure 5, and the snpport will conform vto the shape 'of the tube and beheld from displacement by friction-al engagement withthe wallsof the tube. ln this position, the thermometer will be arranged at the `front portionA of the tube, and thecutaway portionl 34C w ill be arranged. at the rear portionsof the' tube, 'Ihe. thermometer is yadapted to be read'fro'm the rear Qf'the .tubaanda clear View efthe diep4 Inornetei-` vlwillbe had by reasoii of the cutaway portions 34 of the support 31.

The lower cap 16 has an opening 35 in its bottom wall 36, which is bent inwardly, and

this opening is arranged adjacent the ther@ mometer bulb 37. A strip of felt 38 or the like is arrangedin the lower portio'-fth cap 16 to support the thermometer tube, and

ranged Within the casing and secured at a point on the Wall thereof whereby when the casing is rotated, the location of the thermometer will be changed with respect to the supporting arm, in order to be readily observed from Within the vehicle.

6. In a device of the character described, a supporting arm adapted to be clamped to the frame of a vehicle adjacent the windshield thereof, the clamping means being arranged within the vehicle, a, cap secured to the supporting arm, a transparent casing mounted therein, a scale member arranged within the casing and adapted to conform to its general shape and being held therein by frictional engagement therewith, a thermometer attached to said scale member, and means whereby the location of the thermometer may be changed with respect to the supporting arm in order to be readily ob- 20 served from Within the vehicle.
